Chapter 106: Global Catastrophe (Part II)
Seeing the result that appeared on the screen, Tong Shaowei looked surprised, while Luo Jinyong was very calm, as if he had expected this result a long time ago.
"Professor, this ......"
"Have you contacted Zhang Xiaogang?"
Tong Shaowei shook his head. "Communication with Diego Garcia has not been restored, and the American side is also trying to get in touch with Diego Garcia."
Luo Jinyong sighed and said, "It's almost, help me connect and participate in the video conference." ”
Tong Shaowei didn't say anything, and immediately helped Luo Jinyong start the video communication equipment, and then stood outside the shooting range of the camera.
"Professor, have you received a message?" Yang Fanglie asked first. Looks like he's been waiting for a long time.
Also present at the meeting were President Li Xingbang, director of the Military Intelligence Bureau Yuan Dezhi, a large group of ministerial-level officials and high-ranking generals, and several scientists.
"Received it a few minutes ago and I did some of the necessary work."
Yang Fanglie nodded and didn't ask anything more.
"Based on the information obtained now, it is preliminarily certain that the speed of the impact will not exceed a hundred kilometers per second, and the mass of the striking object is about 100,000 tons."
"Is it debris from an asteroid?" Yang Fanglie immediately asked a question.
"Definitely not. All detected debris is intercepted, and even a piece of undetected debris will not have such a low impact velocity. Luo Jinyong paused slightly, "Besides, if it is a piece of debris, then the disaster caused will be global." ”
"If it's not a fragment, what is it?" Li Xingbang also asked.
"I don't know what to do."
"Professor......
"Now, not only does there not have enough data, but there is not even a basis for speculation." Luo Jinyong has long been accustomed to this kind of big scene, and he spoke very directly to Li Xingbang. "If I had to guess, I think there are only two possibilities."
"What are the two possibilities?"
"One is that after the second interception, part of the Debris 0 fell off and hit the Earth. The second is from some unknown object. ”
"What unknown object?"
"We've already calculated that the total mass of the debris is only 1/500 of the 2014X1 asteroid, and we still don't know where the rest of the asteroid is."
"You're saying that the rest of the asteroid is already approaching Earth, and that some of it has fallen off and hit Earth?"
"There is such a possibility, but it is too early to tell."
"Professor......
Luo Jinyong paused a little and said, "I prefer to believe that it is the former possibility, but the No. 0 fragment has already swept over the earth, and the posture is very unstable. If my assumptions are correct, the perigee of Fragment 0 is very low, and when it passes over the Earth, it is clearly disinstilled, and its appearance changes significantly. In other words, even if you take a picture of the Debris 0 now, it will not be possible to compare it to determine whether the part of the Debris 0 that hit the Earth. Theoretically, it is necessary to make an accurate estimate of the mass of fragment 0 before specific conclusions can be drawn. Unfortunately, there may have been significant deviations in the previous mass measurement of fragment 0, and even if the accurate mass of fragment 0 can be measured now, it is impossible to conclude that the impact object must have come from fragment 0. ”
Yang Fanglie sighed and said to a scientist, "Professor Song, can you explain the situation?" ”
Song Wenjie? Luo Jinyong remembered that he was the astronomer who talked about it on TV.
"Professor Luo's analysis is very good, and what is even more regrettable is that we did not find the No. 0 fragment."
"What?" Luo Jinyong's eyes immediately widened.
"The perigee altitude of the Debris 0 is only a little more than a thousand kilometers, and after passing over the Earth, our observatory cannot continue to monitor."
"What about reconnaissance satellites?"
Song Wenjie shook his head and said, "Although the reconnaissance satellite was mobilized, no fragments of No. 0 were found. In addition, so far, no fragment 0 has been found in other countries. ”
"How is that possible?"
"I asked Stark, Sergeyev, Stokes and Renault, among others, and they were also looking for Fragment 0, but they found nothing." Yang Fanglie explained.
Luo Jinyong was silent, although it was unbelievable and made him feel extremely surprised, but he had calmed down.
In the past few days, too many incomprehensible things have happened.
"Professor Luo, when you return to Beijing, you will immediately take over all scientific research projects. Director Yuan Dezhi has already made arrangements, and there are still many things waiting for you to deal with in China. ”
"Mr. Yang, how is the disaster situation in my country?"
"It's not serious."
Luo Jinyong frowned, a little disbelieving.
At this time, another scientist said: "The impact point is on the Northwest Pacific Ocean, that is, on the Pacific plate, and China is located on the Eurasian plate." Japan was hit hard because it was located right at the junction of two tectonic plates. Affected by the buffering effect of the junction of the two major plates, the damage caused by the earthquake to China's local area is not too serious, although some cities, especially the large cities in Northeast China and North China are more seriously affected, but the disaster is not serious, the number of victims is about 100 million, and the number of casualties will not exceed 10 million. ”
"Isn't that serious?" Luo Jinyong knows this scientist, he is a professor at Tsinghua University's School of Geology, Zou Jianbo.
"Compared to Japan, it's not serious."
How do you compare to Japan? Why don't you compare with the United States?
"In fact, relatively speaking, the disaster situation in my country is relatively light." Zou Jianbo paused a little and said, "The United States has not been affected for the time being, but it does not mean that the United States will be spared." As seismic energy is transferred within the plates, the rate of decay is very slow. In about a day, the West Coast of the United States will be affected. If the Pacific plate moves westward as a whole due to the impact, there is a good chance that the coastal areas of the West Coast of the United States will collapse as a whole, and megacities including Los Angeles and San Francisco will sink to the bottom of the sea. ”
"What!?" Luo Jinyong was surprised again.
"It's unlikely, but it's very likely that the Pacific plate as a whole will move northward, and the West Coast of the United States will also be the hardest hit."
Luo Jinyong gritted his teeth, he was not a geologist and could not evaluate Zou Jianbo's speculation.
"Well, now is not the time to discuss these topics, there are more important things to deal with." Yang Fanglie pulled the topic back. "The first thing to do is to assess the disaster situation, predict possible secondary disasters, and make timely preparations for prevention and disaster relief."
"Mr. Yang, I suggest evacuation." Luo Jinyong felt that this suggestion had to be made.
"Evacuation?"
"Cities in coastal areas must be evacuated, as well as large cities in Northeast China, North China, Jiangnan, Southeast China and Central China. I'm not skeptical of Professor Zou Jianbo's scientific reasoning, but we can't take any chances. Within a few days, all sorts of secondary disasters will arrive, and evacuation may lead to large-scale social unrest, but it is much better than leaving people in the city to take risks. Besides, it will only take a few days at most to get the evacuated people home. In any case, I think that city dwellers should be evacuated in time. ”
After Luo Jinyong finished speaking, Zou Jianbo nodded and said, "I agree with Professor Luo's suggestion. The predictions I make are only for the big picture, not for individual situations. If something unexpected happens, even if only one megacity is affected, the consequences are unimaginable. As for the cities in the coastal zone, they must be evacuated immediately. Maybe there won't be an earthquake, but a super tsunami will sweep across the coast in two days. ”
The two scientists shared the same view, which saved a lot of trouble.
Next, several national leaders began to focus on the evacuation efforts.
Yang Fanglie did not participate in the discussion, and several commanders of the services and arms participated in the meeting in his place, because he still had to attend the meeting of the chief of general staff.
Luo Jinyong also did not participate in the discussion of the evacuation work, he had already made suggestions, and the rest of the matter had nothing to do with him.
"Professor, do you want to take a break?"
"No, you sort out the information you received and send it to me." Luo Jinyong lit a cigarette, even though there was a no-smoking sign on the wall in front of him. "In addition, continue to try to get in touch with Diego Garcia and let me know as soon as you find Zhang Xiaogang."
Tong Shaowei nodded, and he handled the work in the aisle outside the rest cabin.
The super tsunami is advancing at a speed of 380 kilometers per hour and will engulf Hokkaido and then the rest of Japan's archipelago in another two hours. After that, the speed of the tsunami will be greatly reduced, but it will still be as high as 100 kilometers per hour, and the height of the waves will be reduced to less than 500 meters. Because the tsunami reflects some of the energy after hitting the Japanese mainland, causing an interference effect, it takes about 24 hours for the tsunami to reach the Okinawa Islands, where it slows down and rises again. By the time it reaches China's eastern coastal areas, the speed of the tsunami will drop to about 60 kilometers per hour and the height will drop to less than 100 meters. The tsunami reaching the southeast and southern parts of China will reach a height of less than 50 meters, even if the speed does not continue to decrease, because it is blocked by the islands of Taiwan and the Philippine Islands.
It can be said that the dense distribution of islands in the western Pacific region has played a crucial role.
In addition, the shallow water depths in the Yellow Sea, the East China Sea and the northern South China Sea also played a significant role in containing tsunamis, especially reducing the height of the tsunami.
It's just that on the other side of the Pacific, the situation is not so ideal.
With no islands blocking it and the average water depth in the North Pacific Ocean being several kilometers deep, a super tsunami will cross the Pacific Ocean without hindrance. By the time it reached the vicinity of the West Coast of the United States, the tsunami was still traveling at a speed of more than 150 kilometers per hour and the water level was above 500 meters. Although the speed and height of the tsunami will decrease before hitting land, it can still sweep through the western coastal plains of the United States.
As long as the US authorities are not too sluggish, the evacuation of residents of the western region has also begun at this time.
Also in need of emergency evacuation are the Russian Far East, the western coast of the American continent, all of Central America, eastern Australia and New Zealand.
As for the many star-studded islands in the Pacific Ocean, all of them will be swallowed up by the tsunami.
Obviously, Japan is the hardest hit area.
After the earthquake, tsunamis followed and will not abate until they hit the Japanese archipelago. This means that, with the exception of a very small number of mountains with an altitude of more than 1,500 meters, the whole of Japan will be engulfed by a tsunami, and the Japanese who will be able to escape will definitely be very rare.
According to Luo Jinyong's estimates, the tsunami will kill at least 400 million to 500 million people.
Luo Jinyong did not dare to jump to conclusions, he was not a geologist and did not know enough about marine disasters.
It's just that Zou Jianbo mentioned a problem that made Luo Jinyong feel very serious. That is, if the Pacific plate moves after the impact.
The Earth's crust is not a monolithic whole, but is made up of several large plates, and underneath the plates is the liquid mantle.
Figuratively, if the earth is not a sphere, but a plane, then the earth's crust is like several wooden planks huddled together floating on the water.
Because the mantle is liquid magma, it has no support for the earth's crust.
As long as there is a sufficiently large external force, the plates that make up the earth's crust will move.
Even in the absence of external forces, the plates move slowly due to their own gravity and internal pressure, and thus create tall peaks.
The earthquake itself is the result of the movement of the plates!
"Professor......
Tong Shaowei came in, and Luo Jinyong immediately looked at him.
"Got in touch with Diego Garcia. After the impact, a magnitude 7.4 earthquake was induced in the Maldives archipelago, and Diego Garcia was less than 500 kilometers from the epicenter. ”
"Can you induce an earthquake from so far away?"
"The Maldives archipelago, where the Indian Ocean plate meets the African plate, is an earthquake-prone area. In addition, strong earthquakes of magnitude 7 or higher have occurred in the southwest of China, all of Indonesia, all of New Zealand, the Gulf region, the Andes region of South America, Iceland in the North Atlantic, the coastal areas of the Mediterranean, East Africa, and the western regions of the United States and Canada. Tong Shaowei paused slightly, and then said, "The State Geological Administration sent a message, through the photos taken by the satellite, it is preliminarily judged that the Pacific plate has moved about a kilometer northward, and the speed of movement is still accelerating, and other plates have also been affected. ”
Luo Jinyong's brows jumped a few times: "How is the situation in Japan?" ”
"Very serious, there is a good chance that Japan will sink!"
"Sunk!?"
"If the Pacific plate continues to move northward, the Japanese mainland will be torn apart, and the land located to the east of the geological fault zone will sink to the bottom of the sea."
Luo Jinyong closed his eyes, he didn't expect this result at all.
"Professor......
"Have you contacted Zhang Xiaogang?"
"Not yet, Diego Garcia's side is extremely chaotic, and there are dozens of casualties among the scientific researchers left, but no one has seen Zhang Xiaogang."
"In any case, get in touch with Zhang Xiaogang as soon as possible."
Tong Shaowei nodded and didn't bother Luo Jinyong again.
Zhang Xiaogang had an accident?
Luo Jinyong was very worried, because the Yankees would not let Zhang Xiaogang go, and might take advantage of the chaos to secretly detain him and then lie that he died in the earthquake.
If Luo Jinyong hadn't left Diego Garcia, the Yankees would have used the same method against him.
It's just that it's useless to be in a hurry.
Actually, Luo Jinyong's worries are a bit redundant.
After the strong earthquake, Diego Garcia was in a mess, and the US military was in a hurry to rescue the injured, and there was no time to pay attention to Zhang Xiaogang.
At this time, Zhang Xiaogang was rescuing injured Chinese researchers with a group of Chinese guards.
After falling in the earthquake, Zhang Xiaogang quickly got up. The first thing that came to his mind was to stay with his own people and not to move alone.
The more chaotic the situation, the easier it is to be plotted.
There are ten commissioners on the island, all of whom are not simple, as well as thousands of agents dressed as guards from ten countries, as well as tens of thousands of American officers and soldiers. At this juncture, if something unexpected happens, such as how many people are missing, such as how many people are killed, I'm afraid no one can say clearly.
Fortunately, the subordinates brought by Zhang Xiaogang are all the backbone of the Military Intelligence Bureau.
More than a hundred people are in a group, even if the Yankees want to deal with them, it is not so easy.
